Preface
This manual serves to explain the use of the hand-held series meters. The models
covered are the pH 11 and the pH 110 hand-held meters.
The manual functions in two ways, firstly as a step by step guide to help the user
operate the meter. Secondly, it serves as a handy reference guide.
This instruction manual is written to cover as many anticipated applications of the pH
meters as possible. If there are doubts in the use of the pH 11/110 meters, do not
hesitate to contact the nearest Authorised Distributor.
It is recommended that all operators should read this manual prior to working with
this instrument. Eutech Instruments / Oakton Instruments cannot accept any
responsibility for damage or malfunction to the meter caused by improper use of the
instrument.
The information presented in this manual is subject to change without notice as
improvements are made, and does not represent a commitment on the part of Eutech
Instruments Pte Ltd / Oakton Instruments.

1 INTRODUCTION
Thank you for selecting the pH 11/110 meter. These meters are microprocessor-
based instruments and are designed to be handy, capable of allowing one-hand
operation. Each has a large custom dual LCD for clear and easy reading. It is a
unique and intelligent instrument that has the capability to cater to the preferences of
the discerning individual. You have one of the two models:
•pH 11 meter
•pH 110 meter
Both meters have many user-friendly features – all of which are completely
accessible through the splash-proof membrane keypad. Your meter includes a
temperature probe, electrode holder, built-in meter stand and batteries. Eutech
Instruments/ Oakton Instruments offer a wide selection of pH and ORP electrodes.
Refer to Section 15 LIST OF ACCESSORIES on page 65 for more information.
The basic model is the pH 11 which is capable of measuring pH, Temperature, and
millivolt (mV).
The deluxe model is the pH 110 which measures pH, Temperature, millivolt (mV) and
relative millivolt (Rel mV). It has many advanced features and allows you to
customise the meter settings. It also has a RS232C port that allows the meter to be
connected to a computer or a printer via a cable for transferring data.
For power requirements, you can either use 4 AAA-sized batteries or an AC/DC
power adapter (sold separately).
Please read this manual thoroughly before operating your meter.

2.2 Keypad
A large membrane keypad makes the instrument easy to use. Each button, when
pressed, has a corresponding graphic indicator on the LCD (Figure 2 on previous
page). Some buttons have several functions depending on its mode of operation.
KEY FUNCTION
OFF
ON
•ON/OFF - Powers on and shuts off the meter. The meter will start in a
measurement mode similar to the last measurement mode it is in before
being switched off.
•CAL - Activates the pH or Relative mV calibration mode and when used
with the MODE key, it activates the temperature calibration mode.
•MEAS - Allows return to measurement mode when canceling or terminating
any operation.
•HOLD - Activates/Deactivates freezing of the measured reading while in
measurement mode.
•ENTER - Confirms the calibration values in Calibration mode and the
selection in SETUP and Print Function mode.
Scroll through the memory location and the stored data during memory
recall.
MI
MR
•MI (Memory Input) - Captures the measured readings of the pH, Relative
mV or mV with its corresponding temperature values and stores them in
the memory.
•MR (Memory Recall) - Retrieves the stored data from memory.
•▲▼ - Sets the calibration values during Relative mV or temperature
calibration.
Scrolls through each SETUP and its sub group menu.
Scroll through Print Function menu and its parameters.
SETUP
•SETUP - Activates the parameter setting menu to allow you to customise
meter configuration, view calibration points and electrode offset data,
select auto power off, reset meter, and clear memory.
MODE
•MODE - Selects the measurement parameter option between pH with
temperature, Relative mV with temperature (only pH 110), and mV with
temperature.
(pH 110)
•PRINT - Allows print of current measurement or stored data to either the
printer or the computer.

3 PREPARATION
3.1 Inserting the Batteries
This meter is packaged with 4 “AAA” alkaline batteries required for operation. To
insert the batteries into the meter, follow the procedure outlined below.
1. To open the battery compartment, press down the catch of the battery cover.
See below.
2. Note the polarity and insert the batteries into the battery compartment
correctly
3. Replace the battery cover into its original position, ensuring the catch is
locked in position.
Your hand-held meter is now ready for operation.

3.2 Connecting the pH Electrode Temperature Probe & Electrode
Holder
The pH 11/110 meter uses any standard pH, ORP, or Ion Selective Electrode (ISE)
with a BNC connector. For Automatic Temperature Compensation (ATC), this meter
requires a temperature probe with a phono-jack connector.
NOTE: It is important that water does not get into the BNC connector. Also avoid
touching the connector with soiled hands.
3.2.1 To connect pH, ORP or ISE electrode
1. Insert the BNC connector
from the electrode over the
BNC connector socket on the
meter.
2. Make sure the slots of the
connector are in line with the
posts of the socket.
3. Slide the BNC connector of
the electrode over (Figure 5).
4. Rotate the connector
clockwise until it locks.
5. To remove electrode, push
and rotate the connector
counterclockwise.
6. While holding onto the metal part of the connector, pull it away from the
meter.
7. Be careful not to use excessive force.
CAUTION: Do not pull on the probe cord or the probe wires might disconnect.
Refer to section 15 LIST OF ACCESSORIES section on page 65 for information on
temperature probe and other electrodes.
Figure 5: Insert the BNC connector from the
electrode cable into the BNC socket on the meter.
